Lori Loughlin and Mossimo Giannulli ‘Checked Out’ of Their 28-Year Marriage ‘a Long Time Ago’

Full House alum Lori Loughlin and designer hubby Mossimo Giannulli are living apart after 28 years of marriage — and sources say their split is poised to turn nasty as they prepare to divide their combined $160 million fortune.

According to insiders, Lori, 61, and Mossimo, 62, who got hitched in 1997, have not filed for divorce — but are currently seeking to sell their $16.5 million Hidden Hills mansion in L.A.

Lori’s rep confirmed the split to People, “They are living apart and taking a break from their marriage. There are no legal proceedings at this time.”

As Globe readers know, the parents of Isabella Rose, 27, and Olivia Jade, 26, did time after pleading guilty to criminal charges related to the Varsity Blues college admissions scandal. Prosecutors say the deep-pocketed duo paid over $500,000 in bribes to have their two kids falsely designated as rowing recruits for the University of Southern California’s crew team to have the girls admitted to the elite school.

Lori was sprung from the slammer in December 2020 after nearly two months in federal prison, while Mossimo served nearly five months before his release in April 2021, per CNN.

Now, an insider says the aftermath of the scandal — and its lingering embarrassment — contributed to their bitter bust-up.

“They both checked out of the marriage a long time ago. They never got over the shame of the whole admissions scandal. That put a wrecking ball through their world,” the insider shares. “They went from being these very outgoing, social, country-club types in Malibu to complete recluses.”

Lori and Mossimo announced their split earlier this month after she was spotted enjoying a cozy dinner and a hug with her Fall Into Winter costar James Tupper, 60. And hours after the breakup news spread, the clothing mogul was seen out with fashion stylist Hannah Harrison, 32, who insists their relationship is platonic, according to Page Six.

Yet, pals say livid Lori is enraged by her estranged spouse spending time with a woman young enough to be their daughter, while Mossimo is believed to be miffed over the possibility of his wife talking about their wrecked romance with Tupper.

“The word is that they do have a prenup, but there will be a lot more to figure out as far as their shared assets,” the insider says. “Right now, they’re finding it difficult to talk without getting into an argument, so they’re trading messages about practical stuff through mutual friends, as well as their daughters, who hate being stuck in the middle.”

Additional sources say the ex-jailbirds never truly recovered from the humiliation heaped on them by their legal nightmare — even though Lori has finally managed to revive her TV career.

“Mossimo says he doesn’t even recognize Lori these days. To hear his take, she’s gotten totally self-obsessed and detached from reality,” the insider shares.

“Ever since she started getting acting roles again, it became all about her career — and Mossimo was a distant second best. She’s equally unimpressed by him and hated how he’d always slope off with his golf buddies and ignore the family.”

The insider adds that Mossimo seems to be mired in a midlife crisis — and he’s been “grating on” Lori’s nerves for a long time.

“It’s no surprise they’ve reached the end of the road, and the fact they can’t stand each other looks like it’ll make for an extremely nasty split — especially with so much money and pride at stake,” the insider observes.

Another source says, “Their marriage was very strong before the sh*t hit the fan with the college admissions scandal. That derailed it.”

That insider also points out after the pair’s guilty pleas, Mossimo’s product sales suffered and Lori lost her regular role in Hallmark’s When Calls the Heart franchise. The source adds, “They blamed each other, but he blamed her more.”

Now, the insider says Lori is telling people that she’s glad she won’t have to deal with Mossimo’s behavior anymore, but adds, “He’s pointing fingers and furious that she’s gotten so cozy with her costar James. She swears it’s all innocent and that he’s only a friend, but Mossimo doesn’t buy it. There’s zero trust left, and now they have to divide up $160 million in assets. There’s no way it doesn’t get ugly.”
